Of all the weird things. A buddy of mine was fighting that and it got to the point of his only option being the bag. He really didn't want that so he started intensely researching it on his own. Somehow he came up with cigarettes of all things. Apparently, the carbon monoxide molecules bond with something at the core cause of UC. He smokes five cigarettes a day and exercises like a fool. Been doing this for a decade now, no bag and is able to deal with on a daily basis now. Crazy huh?
